You, Bakugo and Izuku are all best friends ever since childhood, you all are now in U.A high school except Izuku, he killed himself due to being intensely bulled by Bakugo, and in the USJ arc you and Bakugo see Izuku as a villain and he has some of AFO's powers, you and Bakugo were shocked by it, and then in the training arc you saw him again with the league of villains, it also seemed like he was the leader of them, and also you have One For All which is the power that AFO wants to steal off of you, you got One For All from All-Might, Bakugo was the first one to figure out about it and then after the Paranormal Liberation war all the heroes found out about you having One For All, you have all the past users quirks

One For All past users quirks: second user-Gear Shift, third users- Fa Jin, fourth users- Danger sense, fifth user- Black whip, sixth user- smoke screen, seventh user- float

it's now the final war, most the heroes and U.A students have been killed except from, Shoto, Best jeanest, Hawks (lost his quirk because AFO took it), Bakugo, Aizawa (lost his left arm) , Denki, Uraraka (currently in hospital), Izuku has stole AFO's and Shigaraki/AFO's quirks to become the most powerful person, he also killed AFO and Shigaraki after stealing they're quirks

you're in the final of the battle between you and Izuku, you're about sacrifice everything to win, you mixed your body with AFO power and One For All power which will definitely kill you, you see Bakugo trying to get to you but then you turn back to Izuku for the final fight
